G RATE-BAR.

SPECIFICATION forming part of Letters Patent No. 303,675, dated August19, 1884.

Application filed April 19. 1884. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM Soi/r, a eitizen of the United States,residing at Freeland, i in the county of Luzerne and State ofPennsylvania, have invented a new and useful Grate-Bar, of which thefollowing is a speciiication, reference being had to the accompany ingdrawings.

rlhis invention has lrelation to adjustable ventilator grate-bars forboiler-furnaces; and it consists in the construction and novelarrangement of parts, as will be hereinafter fully described, andparticularly pointed out in the claims.

Figure 1 is a view in perspective of the channeled perforated grate-barwith the iinger-sections removed. Fig. 2 is a plan View with thelinger-sections in place. Fig. 3 is a vertical longitudinal sectionalView on the line x x in Fig. 2, and Fig. 4 is a transverse sectionalview on the line y y i'n Fig. 2.

Referring by letter to the accompanying drawings, A designates thechanneled perforated ventilator grate-bar, which is in the shape incross-section at its middle portion of an inverted U, thedownwardly-projecting flanges or side walls, BB, being curved from endto end, as shown. This bar A is provided at its ends with thebearing-bars C C, whi h are built into the walls of the furnace in theusual manner. These bearing-bars `or end plates, C C, are provided inthe inner edges with seats D, for the reception of the end iinger of thenger-sections E and F. The arc-h or top of the grate-bar A is providedwith mortises G, H, I, and K, for the reception of `tenons L on thetransverse bars M of the iinger-sections E, F, and N. The middleiingers, O O', of the end finger-sections are made sectional, one part,O, being cast withthe channeled bar A. The top of the bar A is providedwith a line of vertical perforations, P, for Ventilating the bar andgrate-finger sections, and also to keep the bar A cool, and

last for years on this account. Then either of the iinger-sectionsbecomes burned so as to be worthless, the iire may be moved from it ontoanother section of the grate, and with the handle-tongs the worthlesssection may be quickly removed and replaced by a new one without pullingout the fire. rEhe bar Ais provided at each side of the mortises withlaterally-extending shoulders R, which form the bearings for thetransverse bars of the grate` sections. The ends of the sections arepreferably made curved, as shown, for convenA ieuee in removing andreplacing the sections.

This grate-bar can be made of any kind of suitable metal, and is cheap,simple, and durable. The curved ends also prevent the scraper or pokerfrom dropping into the openings between the sections and becoming fastwhen being moved backward and forward over the grate.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is*- l.lheehanneled and perforated bar A,pro vided with end plates, G C, havingseats D, and the mortises and laterally-extendin g shoulders at theirsides, in combination with the detachable iingenseetions having theirtransverse bars provided with tenons, substantially as speei lied.

2. The combination, with the channeled and perforated grate-bar A,having the middle iinger-sections, Ol, cast thereon, of the end sectionsprovided with a section of the middle linger, substantially asspecified.

`In testimony that I claim the foregoing as my own I have hereto ailixedmy signature in presence of two witnesses.
